STROPPING MECHANISM FOR RAZORS.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 30. 1904. Serial No. 200.725.

To all whom it may concern:

Be it known that 1, HENRY J. QAISMAN, a citizen'of the United States, and resident of New York city, borough of Manhattan, New York, have invented certain new and useful Improvements in Stropping Mechanism for Razors, of which the following is a specification.

My invention has for its object to permit a safety razor blade to be stropped Without removing it from its holder in the razor frame.

To this and other ends my invention comprises the novel details of improvement that will be more fully hereinafter set forth and 'then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a plan view of my improvement mounted upon a strop ready for use, Fig. 2 is a side elevation, looking from the lower part of Fig. 1, Fig. 3 is a cross section, substantially on the line 3, 3, in Fig. 1, looking in the direction of the arrows, Fig. 4 is a longitudinal section, substantially on the line 4, 4, in Fig. 1, looking in the direction ofthe arrows, and Fig. 5 is a side view of a safety razor frame shown in the other views.

Similar numerals of reference indicate correspondingparts in the several views.

rIfhe main frame of the device comprises a base member or plate 1 and sides 2, 3, which may be struck up from suitable sheet metal, said sides being so spaced as to receive a strop 4 between them. At 5 are indicated rollers located between and carried by the sides A 2, 3,'and said rollers are shown secured on shaftsi journaled in the upwardly extending members of the sides 2, 3, said rollers being locatednear opposite ends of the main frame, the strop 4 being adapted to pass through the frame beneath said rollers and in contact therewith, so that as the frame is reciproeated along the strop the rollers 5 will be oscillated to rock the razor blade 7. The means I have shown for causing the blade 7 to be rocked by said rollers comprise racks and gears arranged as followsz-To the rollers 5 are secured gearsY 8 that mesh' with racks 9 carried by a sliding bar or frame 10 guided upon the main frame, as by a guiding plate 11 shown provided with an inturned lower bearing web 11 (see Fig. 3), which plate 1]: may' be hung on the shafts 6. The main frame is the-racks 9 and 14. As shown in Fig. 2 the racks 9 mesh with the under sides of the gears 8 and the rack 14 meshes with the upper side of the gear 13, which is designed for causing the blade edge to be thrown in the direction opposite to that in which the device travels along the strop. Thus, when the device travels from left to right in Fig. 1, along the strop, the rollers 5, which bear on their under surface upon the strop, are caused to'rotate by the strop and will, through the racks and gears, throw the blade holder or carrier 12 and the blade 7 toward the left, and when the device is moved in the reverse direction said rollers and the 'gears and rac'ks will throw the blade in the reverse direction, so that at all times the blade will drag on the strop behind the carrier or holder 12. 1d indicates handle members on the main frame for reciprocating it. To cause the rollers 5 to bear firmly upon the strop so as to produce the required friction for rocking said rollers, as the device is reciprocated along the strop, I

provide rollers 17 that bear against the under surface of the strop and are pivotally carried, as shown in Figs. 3 and 4, by a plate spring 18 attached centrally to the base member 1 ofthe main frame and having anormal spring tendency to push the rollers 17 against the strop. The rollers 17 are supported upon rods 19 that are carried by yokes or frames 2O secured to the spring 18 (see Figs. 3 and 4.) In the arrangement shown the rollers 17 are located at lone side, respectively, of a line passing vertically (in Fig. 4) through the axes of rollers 5, so as to have a tendency 'to bend the strop as it passes under the rollers 5 to cause an increased gripping action between the strop and said rollers. As shown in the drawings, the blade carrier or holder 12 is of tubular form provided with a longitudinally disposed groove or channel 12 that opens through one side thereof, as in Fig. 4, and also opens through the end thereof opposite the gear 13, as indicated in Fig. 3, to enable the blade holder of a safety razor to slide therein in a longitudinal direction. his warrangement permits ofthe attachment to the de holder 12 of a blade or blade holder while it remains in the frame of a safety razor so that it is not necessary to remove the blade from such razor frame in order to strop the blade by means of my improvements. In .other words, my improved stropping device is arranged to have a safety razor frame and its attached blade applied in such manner that the complete safety razor will be supported and carried by the frame of the stroptubular portion 24 of a holder which carries the blade l 7, and said tubular portion 24 ofthe blade holder is adapted to slide into the open end of the carrier 12 in the position shownin Fig. 3. As shown in Figs. 3 and 5 the razor blade holder 24 has a yoke member 25 secured to the tubular member 24,V the blade 7 being sef cured between' the lugs 25'L of said yoke, pins 26 on the yoke'entering corresponding sockets in the blade, a screw 27 carried by a lug 25*L and entering the socket in the blade serving to detachably and rmly hold the blade in its holder. But other well known means l may be provided for receiving the blade on its holder.

The base part 220i the razor frame is adapted to be attached to the base member 1 of the stropping device frame at the same time that the razor blade holder 24 is in position in the blade holder or carrier l2 of the 25 stropping device, and to this end I have shown the base l provided with guides l",V extending 'trans versely of 'said base and 'adapted to permit base part 22 to slide therein transversely of frame l, (see Figs.-

2 and 4.) The arrangement of the parts is such that when the blade is to be stropped the base 22 of the razor frame is placed at one. side of the main frame in une with the guides 1a of the latter and the shaft 2s and tubular member or sleeve 24 are also lalined with vthe socket or guide of holder 12, and then the razorframe is pushed toward the main frame so that the razor `frame will be secured to Vthemain frame, the base plate 22 thus being held by guides 1a and the blade 7 connected with the carrier l2 to rock therewith, as indicated in 3, the razor frame thus being firmly mounted on the main frame. In such position of the parts (the razor frame being supported and carried by the main frame), the blade 7 will be caused to rock as the device is reciprocated along the strop in manner before described.

i In order that the razor frame may be connected -with the frame of the stropping device without interference, I connect'the blade guard 28 movably with the razor frame so that said guard n'iay be thrown down from its shaving position with respect to the blade edge, as indicated in Figs.` 2, 3 and 4, when the blade is to be stropped so as to leavea free space betweenl the base part 22 of the razor frame and its blade holder 24. As shown, the guard28 is pivotally supported by the razor. frame on pivots 29 that pass through lugs 28a on the guard and through lugs or ears 30 on a bar 3l secured upon an extension 32 of the base 22, a rivet 33 being shown holding Ithe parts 31 and 32 rmly together. The

guard 28 is shown provided with lips 28h that are adapted to engage the edge of the razor bladev for holding the edge in shaving position with respect to the guard, and to hold said guard in shaving position I provide a spring 34 that is shown clamped between the bar 31 and the extension 32 by the rivet 33, and the ends of said spring are adapted to be engaged by the edges 23 .65 ol the lugs 28 of the guard when the guard is pressed up in shaving position against the blade edge so that the tendency of said spring is to push the lips 28b against the blade edge to hold the guard firmly in position. When the blade is to rock, the guard is swung back on its pivots in position to hang below the base l of the main frame to permit the 'ready insertion of the razor frame into the main frame as indicated in Figs. 2 and 4, in which position the edges 28l of lugs 28tfliear on spring 34 to hold the guard in the lowered position.

The advantages of my improvements are that the stropping devices mayremain mounted upon the strop so that during the operation of shaving, when it is required to strop the blade, it will merely be necessary to move back the guard 28 and without removing the blade from the razor frame apply the frame and the razor to the stroppingl device in the manner described and then reciprocate the device having the attached razor along the strop, then when the blade is stropped Withdraw the razor frame and blade from the stropping device, adjust the guard to the blade and proceed with shaving.
